High-permeability metal cutting fluid with excellent corrosion resistance and preparation method of metal cutting fluid

Abstract

The invention discloses a high-permeability metal cutting fluid with excellent corrosion resistance. The high-permeability metal cutting fluid is characterized in that the metal cutting fluid is prepared from raw materials in parts by weight as follows: 1-2 parts of ammonium dihydrogen phosphate, 2-3 parts of magnesium sulfate, 2-5 parts of silica powder, 4-5 parts of tricresyl phosphate, 1-2 parts of tert-butylhydroquinone, 8-10 parts of oleic acid, 2-3 parts of epoxy castor oil, 1-2 parts of hexamethyleneimine, 1-2 parts of phenyl naphthylamine, 1-2 parts of nekal, 1-2 parts of polyacrylamide, 5-7 parts of an auxiliary and 150-180 parts of water. The auxiliary added to the cutting fluid enhances the dispersion, lubrication and film-forming property of the cutting fluid; the added phenyl naphthylamine, tricresyl phosphate and nekal can improve the infiltration capacity and the corrosion inhibition capability of the cutting fluid; the cutting fluid has lubrication, mould-proofing and wear resistance property, is non-toxic and odorless and doesn't corrode a human body and equipment or pollute the environment, and the performance of the cutting fluid is greatly improved.

Description

technical field [0001] The invention relates to the field of cutting fluids, in particular to a metal cutting fluid with excellent high penetration anticorrosion performance and a preparation method thereof. Background technique [0002] Cutting fluid is an industrial liquid used to cool and lubricate cutting tools and workpieces during metal cutting, cutting and grinding. According to its medium condition, it can be divided into oil-based cutting fluid and water-based cutting fluid. Oil-based cutting fluid has good rust resistance and lubricity, but its biodegradability is poor, and it pollutes the environment. The cracked products during use are harmful to organisms, and the overall cost of its production Higher, does not meet the requirements of energy conservation and environmental protection. Water-based cutting fluid has good cooling performance and cleaning performance, and the cost is lower than oil-based cutting fluid, and the pollution is small. In the process o...

Problems solved by technology

However, although some water-soluble cutting fluids have good cooling performance, their anti-rust and anti-corrosion effects are poor. The reason is that the residence time on the workpiece surface is short and the permeability is poor.
